The Saint goes to investigate a plane crash in an English field. The pilot's disappeared, leaving large amounts of forged bank notes. Templar tracks down the pilot's home, only to discover the man's been killed. Simon locates the dead man's fiancée in Paris. Clues lead Templar to the villa of a countess, who's not only a counterfeiter, but something of a counterfeit herself.
